#jarchi - This script modifies a visual relationship to create an orthogonal L-shape

RelLshape.Ajs

 * This script takes a selection of visual objects as input, filter it to keep only relationships

Thank you, very helpful. I have been thinking about such script, but could not figure out how to implement it.
